Zusammenfassung

EGARCH models for conditionally heteroscedastic time series have attracted a steadily increasing degree of attention in financial econometrics and related fields. These models are able to represent some of the stylized features of financial returns, such us uncorrelation in levels but strong dependence in squares and log-squares and leverage effect. Estimation of these models may be carried out by maximum likelihood and Whittle methods. This paper compares the finite sample behaviour of both methods, confirming that maximum likelihood is more efficient but bivariate Whittle sometimes performs comparably
